Description

Technical Field

[0001] The present invention relates to the technical field of disinfection, and more specifically, the present invention relates to a disinfection device and method for vegetable seeds before sowing. Background Art

[0002] Many diseases of crops are transmitted through seeds (seed-borne diseases). With the frequent transportation of seeds and the increasing number of supply channels, the possibility of the spread of dangerous diseases, pests and weeds is constantly increasing. In order to eliminate the germs attached to the seeds, control seed-borne bacteria, prevent the introduction of dangerous diseases, further reduce the incidence in the field, reduce the losses caused by diseases to production, and ensure sowing safety and increase crop yields, seed disinfection before sowing or before germination is one of the effective methods for preventing crop diseases.

[0003] At present, there are many methods for seed disinfection. For some vegetable seeds, such as wax gourd, spinach, cucumber, etc., their seed coats are hard, difficult to absorb water, and can tolerate high temperatures. Using high-temperature sterilization is often more suitable than other methods. However, vegetable seeds need to be cleaned before disinfection. For a large number of seeds, manual continuous turning is required during cleaning to clean them thoroughly, which is labor-consuming. Secondly, for high-temperature disinfection, the seeds are stacked on top of each other, resulting in inconsistent temperatures between the inner and outer layers of the seeds piled up together, and at the same time, complete disinfection cannot be achieved.

Detailed implementation mode

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0037] Refer to the specification appendix Figure 1-10 , Embodiment 1: A disinfection device for vegetable seeds before sowing, including a central box assembly 1, as Figure 1 shown, the central box assembly 1 is arranged in a cavity shape with the mouth facing upwards. A mounting plate is fixedly installed at the bottom end of the central box assembly 1. A stepping motor 10 is mounted on the top end of the mounting plate. The end of the output shaft of the stepping motor 10 is fixedly connected with a group of embedded straight row racks 9, and the embedded straight row racks 9 are slidably installed inside the central box assembly 1;

[0038] As Figure 1 shown, a plurality of meshing assemblies 8 are installed through the inside of the central box assembly 1. The plurality of meshing assemblies 8 and the embedded straight row racks 9 are arranged in a meshing state. It should be mainly noted that the multiple meshing assemblies 8 do not contact each other and are not meshingly connected. Each group of meshing assemblies 8 penetrates through both ends of the side wall of the central box assembly 1 and is fixedly connected with a connection end 12;

[0039] As Figure 8As shown, a seed loading box assembly 14 is internally inserted into the connecting end 12. The seed loading box assembly 14 includes two sets of built-in circular ends 1401, which are hinged between the two sets of built-in circular ends 1401. A frame 1403 is fixedly installed at one end of each set of built-in circular ends 1401 away from the connecting end 12. The frame 1403 is a rectangular frame. Multiple steel plates 1404 are welded inside the frame 1403 and are arranged in a staggered manner. A gauze 1405 is fixedly connected inside the squares separated by the multiple steel plates 1404 in a staggered manner.

[0040] In a specific implementation, the model of the stepper motor 10 is BS42HB33 - 01. The stepper motor 10 serves as a driving source. When the stepper motor 10 is turned on, the end of the output shaft of the stepper motor 10 drives the embedded straight rack 9 to displace relative to the axis of the horizontal center line of the central box assembly 1. When the embedded straight rack 9 undergoes horizontal displacement, it meshes and drives with the meshing assembly 8, thereby causing the meshing assembly 8 to drive the connecting end 12 and the seed loading box assembly 14 to rotate synchronously.

[0041] Specifically, the disinfection steps for cooked vegetable seeds are as follows: First, the cooked vegetable seeds need to be rinsed, and the rinsed cooked vegetable seeds are dried, and then high-temperature treatment is carried out for disinfection.

[0042] As Figure 1 shown, there is a cavity inside the side wall of the central box assembly 1. The top of the central box assembly 1 is connected to a plurality of spraying assemblies 7. The plurality of spraying assemblies 7 correspond to the plurality of meshing assemblies 8 one by one. The spraying assembly 7 is connected to a connecting pipe 6 through the central box assembly 1. One end of the connecting pipe 6 is installed with a vacuum pump 5, and a thermostat 4 is inserted at the bottom end of the vacuum pump 5.

[0043] Among them, since there are multiple groups of spraying assemblies 7, to prevent the temperature of several groups of spraying assemblies 7 far from the thermostat 4 from decreasing during the transmission of water flow or disinfectant solution, a thermostat plate is attached to the side wall of the central box assembly 1 to keep the temperature of the water flow constant during transmission. Secondly, the vacuum pump 5 is a suction pump, mainly used to extract the air inside the thermostat 4 and the constant temperature water inside the thermostat 4. The model of the vacuum pump 5 is TM30B - A vacuum suction pump, and the model of the thermostat 4 is JSQ20 - 10HWA.

[0044] Example 2: As Figure 10 shown, the spraying assembly 7 includes a U-shaped elbow 701. One end of the U-shaped elbow 701 is connected to a pipe connection base 702. A plurality of circular nozzles 703 are fixedly installed at the bottom end of the pipe connection base 702. The water flow passes through the U-shaped elbow 701 and the pipe connection base 702 and then is sprayed through the circular nozzles 703.

[0045] Specifically, the end faces of the two sets of steel plates 1404 located inside the two sets of frames 1403 are attached to each other. At the same time, the steel plates 1404 are made of hollow steel plates, ensuring a certain strength while keeping the quality light. At the same time, independent cavities are formed inside the squares surrounded by multiple staggered steel plates 1404 under the wrapping of the gauze 1405. The cavities prevent the cooked vegetable seeds from moving in position during the turning of the seed loading box assembly 14.

[0046] The specific operation is as follows: Vegetable seeds are filled inside the seed loading box assembly 14. Shake the built-in circular end 1401 to prompt the cooked vegetable seeds laid inside the built-in circular end 1401 to enter the squares surrounded by multiple staggered steel plates 1404. Close the two sets of built-in circular ends 1401 to fix the positions of the vegetable seeds, and then insert the seed loading box assembly 14 into the inside of the connection end 12 for fixation synchronously.

[0047] Open the vacuum pump 5 to allow the cleaning liquid inside the constant temperature box 4 to enter the inside of the spraying assembly 7 through the side wall of the central box assembly 1, and then spray it out through the circular nozzle 703. Synchronously open the stepping motor 10 to prompt the seed loading box assembly 14 to rotate synchronously with the connection end 12, so as to ensure that each vegetable seed is cleaned. Compared with the traditional large-batch cleaning method, manual continuous turning of the cooked vegetable seeds is required to ensure the surface cleaning of the cooked vegetable seeds is perfect. Secondly, for different seed characteristics, the seed coats of many seeds are relatively thin, and the seed coats will be damaged during the turning of the seeds.

[0048] As Figure 7 shown, a water flow receiving box 2 is arranged at the bottom of the spraying assembly 7. The water flow receiving box 2 is arranged in a cavity shape with the mouth facing upward. A plurality of rigid balls 11 are arranged at the bottom of the water flow receiving box 2, and the rigid balls 11 are used to facilitate the movement of the water flow receiving box 2.

[0049] During the flushing process, the water flow receiving box 2 is used to receive the dirty water flowing down from the flushing of the vegetable seeds.

[0050] After the flushing process is completed, remove the vacuum pump 5 from the top of the constant temperature box 4, turn on the vacuum pump 5 to prompt the vacuum pump 5 to extract the external air and blow it out through the vacuum pump 5 - the inner cavity of the side wall of the central box assembly 1 - multiple spraying assemblies 7. During the flow of the air flow, the inside of the vacuum pump 5, the inner cavity of the side wall of the central box assembly 1, and the U-shaped bend 701 are dried, preventing the cleaning liquid from mixing with the disinfectant required later. Secondly, the blown air flow is used to dry the vegetable seeds located inside the seed loading box assembly 14.

[0051] As Figure 6As shown, the central box assembly 1 includes a central box body 101. Four sets of legs 102 are vertically inserted at the bottom end of the central box body 101. A slot 103 runs through the bottom end of the central box body 101, and the embedded straight rack 9 is slidably installed inside the slot 103.

[0052] As Figure 3 shown, the meshing assembly 8 includes a rotating cross bar 801. An annular gear 802 is fixedly installed on the surface of the rotating cross bar 801. The annular gear 802 and the embedded straight rack 9 are arranged in a meshing state.

[0053] As Figure 2 shown, four side plates 1402 are installed on the surface of the built-in circular end 1401, and there are gaps between each set of side plates 1402;

[0054] As Figure 2 shown, a fixing assembly 13 is engaged inside the connecting end 12. The fixing assembly 13 includes an annular sleeve 1301. Four cylindrical telescopic insertion rods 1302 are horizontally inserted inside the annular sleeve 1301. One end of the cylindrical telescopic insertion rod 1302 away from the central box assembly 1 is fixedly connected with an arc-shaped clamping plate 1303, and the arc-shaped clamping plate 1303 is engaged inside the side plate 1402.

[0055] Specifically, since the seed loading box assembly 14 is inserted inside the connecting end 12, there is a risk that the seed loading box assembly 14 will disengage from inside the connecting end 12 during rotation. The fixing assembly 13 is engaged inside the connecting end 12 and is rotatably connected inside the connecting end 12. The four cylindrical telescopic insertion rods 1302 can rotate around the horizontal center line of the annular sleeve 1301. Among them, pull the arc-shaped clamping plate 1303 to make the arc-shaped clamping plate 1303 in the same plane as the gap of the side plate 1402, and then slide the cylindrical telescopic insertion rod 1302 to make the arc-shaped clamping plate 1303 just engaged inside the side plate 1402. The elastic force generated by the stretching of the cylindrical telescopic insertion rod 1302 ensures the tight connection between the connecting end 12 and the seed loading box assembly 14, preventing the seed loading box assembly 14 from disengaging from inside the connecting end 12.

[0056] Example 3: As Figure 9 shown, a reinforcing assembly 15 is inserted on the surface of the seed loading box assembly 14. The reinforcing assembly 15 includes a columnar base 1501. The columnar base 1501 is fixedly inserted on the surface of a set of frames 1403. A rectangular telescopic plate 1502 is rotatably connected to the surface of the columnar base 1501. A clamping post 1503 is engaged inside the rectangular telescopic plate 1502, and the clamping post 1503 is fixedly connected to the surface of another set of frames 1403.

[0057] Among them, by fitting the rectangular telescopic plate 1502 into the inside of the clamping post 1503, the two sets of frames 1403 are closely fitted. The rectangular telescopic plate 1502 is an elastic telescopic plate. When the two sets of frames 1403 are in a closely fitted state, the rectangular telescopic plate 1502 is in a stretched state.

[0058] As Figure 1 shown, a circulating pipe 3 is connected to the bottom side of the water flow receiving box 2 on one side of the vacuum pump 5, and the other end of the circulating pipe 3 is inserted into the inside of the constant temperature box 4.

[0059] After the drying process is completed, adjust the angles of the multiple seed loading box assemblies 14 to make the seed loading box assemblies 14 in a vertical state. Insert the circulating pipe 3 and the vacuum pump 5 into the inside of the constant temperature box 4. The vacuum pump 5 pumps the water flow inside the constant temperature box 4 upward. The water flow passes through the central box assembly 1 and the spraying assembly 7 and is sprayed onto the surface of the vertically placed seed loading box assemblies 14. The water flow passes through the seed loading box assemblies 14 to soak the vegetable seeds, and then drips into the inner cavity of the water flow receiving box 2 and circulates to the inside of the constant temperature box 4 through the circulating pipe 3. The water flow circulates continuously to irrigate the vegetable seeds continuously.

[0060] A disinfection method for vegetable seeds before sowing includes the following steps:

[0061] S1: Vegetable seeds are filled inside the seed loading box assembly 14. Shake the built-in circular end 1401 to make the cooked vegetable seeds laid inside the built-in circular end 1401 enter the squares formed by the multiple staggered steel plates 1404. Then insert the seed loading box assembly 14 into the inside of the connecting end 12 for fixation, and use the fixing assembly 13 to clamp and fix the position of the seed loading box assembly 14.

[0062] S2: A cleaning liquid is filled inside the constant temperature box 4. Insert the vacuum pump 5 into the top of the constant temperature box 4. Turn on the vacuum pump 5 to make the cleaning liquid inside the constant temperature box 4 enter the inside of the spraying assembly 7 through the side wall of the central box assembly 1 and be sprayed onto the surface of the seed loading box assembly 14 through the circular nozzle 703. Synchronously turn on the stepping motor 10 to make the seed loading box assembly 14 rotate synchronously with the connecting end 12. The seed loading box assembly 14 is cleaned during continuous flipping.

[0063] S3: Withdraw the vacuum pump 5 from the top of the constant temperature box 4. At the same time, mount the vacuum pump 5 on the desktop or a horizontal platform, and do not block the air inlet of the vacuum pump 5. Turn on the vacuum pump 5 to make the vacuum pump 5 extract the external air and blow it out through the vacuum pump - the inner cavity of the side wall of the central box assembly 1 - the multiple spraying assemblies 7 to dry the vegetable seeds located inside the seed loading box assembly 14.

[0064] S4: Turn off the stepper motor 10, replace the liquid inside the thermostat 4, insert the vacuum pump 5 into the top of the thermostat 4 again, and synchronously insert the circulation pipeline 3 into the inside of the thermostat 4 to achieve the circulation of water flow. Adjust the angles of the multiple seed loading box assemblies 14 to make each group of seed loading box assemblies 14 in a vertical state. Turn on the vacuum pump 5 to pump the water flow inside the thermostat 4 upwards to the surface of the seed loading box assembly 14 for spraying. The disinfectant solution sprayed on the vegetable seeds falls into the inner cavity of the water flow receiving box 2 due to gravity and is recycled into the inside of the thermostat 4 through the circulation pipeline 3 again to complete the seed soaking step.

9. The disinfection device for vegetable seeds before sowing according to claim 4, characterized in that: The water receiving box (2) is located at one side bottom of the vacuum pump (5) and is communicated with a circulation pipeline (3). The other end of the circulation pipeline (3) is inserted inside the constant temperature box (4).

10. A method for disinfecting vegetable seeds before sowing according to claim 1, characterized in that, It includes the following steps: S1: Vegetable seeds are filled inside the seed loading box component (14). The built-in circular end (1401) is shaken to prompt the cooked vegetable seeds laid inside the built-in circular end (1401) to enter the squares surrounded by multiple staggered steel plates (1404). Then, the seed loading box component (14) is synchronously inserted into the connection end (12) for fixation. The position of the seed loading box component (14) is fixed by engaging with the fixing component (13). S2: Cleaning liquid is filled inside the constant temperature box (4). The vacuum pump (5) is inserted into the top of the constant temperature box (4). The vacuum pump (5) is turned on to make the cleaning liquid inside the constant temperature box (4) enter the spraying component (7) through the side wall of the central box component (1), and is sprayed onto the surface of the seed loading box component (14) through the circular nozzle (703). The stepping motor (10) is synchronously turned on to prompt the seed loading box component (14) to rotate synchronously with the connection end (12). The seed loading box component (14) is cleaned during continuous flipping. S3: The vacuum pump (5) is removed from the top of the constant temperature box (4). At the same time, the vacuum pump (5) is mounted on a table or a horizontal platform. Do not block the air inlet of the vacuum pump (5). The vacuum pump (5) is turned on to prompt the vacuum pump (5) to extract the external air and blow it out through the vacuum pump (5) - the inner cavity of the side wall of the central box component (1) - multiple spraying components (7) for drying the vegetable seeds located inside the seed loading box component (14). S4: Turn off the stepper motor (10), replace the liquid inside the incubator (4), insert the vacuum pump (5) into the top of the incubator (4) again, synchronously insert the circulation pipeline (3) into the inside of the incubator (4) to achieve the circulation of water flow, adjust the angles of multiple seed loading box assemblies (14) so that each group of seed loading box assemblies (14) is in a vertical state, turn on the vacuum pump (5), pump the water flow inside the incubator (4) upwards to the surface of the seed loading box assembly (14) for spraying, and the disinfectant solution sprayed on the vegetable seeds falls into the inner cavity of the water flow receiving box (2) due to gravity, and then circulates back into the inside of the incubator (4) through the circulation pipeline (3) to complete the seed soaking step.
